RIKEN Center for Quantum Computing (RQC)
Director: Yasunobu Nakamura (Ph.D.)
The RIKEN Center for Quantum Computing (RQC) is an internationally unique research organization that develops and owns actual quantum computers based on different approaches, such as the superconducting quantum computer, including the first domestic quantum computer “A”, and the world's first general-purpose optical quantum computing platform.
The RQC develops and improves the performance of actual quantum computers based on various approaches such as superconductivity, optics, semiconductors, and cold atoms. While integrating cutting-edge physical science, information science, computer science, optics, and electronics technologies, the RQC expands the range of computational possibilities to solve social issues and promotes research to establish next-generation quantum computer technologies.
